I was just in the process of changing SteamVR versions, I’d uninstalled SteamVR to test LH still track without it installed (They do!). I just put it back on tested fine… switched to SteamVR beta… all OK then suddenly ‘blip’… so very little movement of the HMD at all really… just sat at my desk, on my head and left screen did that.

Also been very careful with it, so its not a knock/drop/heavy movement that’s involved.

Can you set the screen to extended mode? Similar to the vive? Does the White part change shape or move at all? @spamenigma

Your gonna wanna get a suction cut and see what this artifact looks like without the lens. I will tell you it’s VERY unlikely the display itself is broken. I’ve transported more displays (repaired a few) than I can count. Those things can take beating after beating lol. My guess is something holding it shifted possibly.

Also repaired a few hardware digital upscaler/framerate converters and I’ve never seen one “partially send an image” if it’s broken.

EDIT:
Good Advice: The current gen (low FOV) is like playing the 8K with the edges blocked (aka it will look slower).
Bad Advice: If you want your game to look faster, just block the center of your vision and only show the edges.

Pentile has a 1/3 less subpixels so SDE is more prominent because of this.

OK, but the Vive Pro also got better SDE than the OG despite pentile. It would be interesting to know if it would be worse and if, how much. I mean compared to the vive pro, the 5k BE variant
(much higher FOV, slight better SDE-due more Res, same good colors)
vs the 5k+
(much higher FOV, better SDE-due different panel tech, worse colors)
does not sound bad?

Well for SDE has 2 components in vr subpixel layout can affect it. However there is also pixel density.

Not accurate but consider ppi of say 500 per inch on a 5" display. At 5" it will have no see able sde regardless of panel type with no magnification. However magnify it with lenses to be like a 100" screen & the ppi is now 5 ppi (500/100). SDE is now more considerably noticeable.
